SPECIFICATION formingpart of Letters Patent N o. 687 ,770, datedDecember 3, 1901.

Application filed semester 23, min. sate No. 763140. (No model.)

To aZZ whom it may concern/.-

. Be it known that I, CHARLES R. MCGOWAN, a citizen of the UnitedStates, and a resident of Taunton, county of Bristol, State ofMassachusetts, have invented an Improvement in Weighting-Mechanism forDrawing or Spinning Frames, of which the following description, inconnection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention relates to the mechanism for weighting the topdrawing-rollers of drawing and spinning frames; and it has for itsobject the simplification and cheapening of such mechanism,withincreased efficiency and convenience of operation.

My invention applies more particularly to drawing or spinning frameswherein the top drawing-rollers are coveredwith leather or similarmaterial of such character that it is necessary to relieve the rollersof weight when the frame is not in operation.

In relieving the weight it is undesirable to disconnect theweight-hooks, and the latter shouldnot be permitted to turn in eitherdirection, nor should they be so constructed as to permit thepossibility of a chan'gein length, as would be the case if screws andnuts are employed in their construction.

The various novel features of my invention will be hereinafterdescribed, and particularly pointed out in the following claims.

- Figure 1 is a transverse section of a portion of a drawing or spinningframe with one embodiment of my invention applied thereto, and Fig. 2 isa front elevation of a portion of the apparatus illustrated in Fig. 1.

The journals a'of the top drawing-rollers A have suspended therefrom thehooks H, which are shown as thin flat plates, the lower end of eachhaving a hole h therein, Fig. 2, to be engaged by the upper end of alink I), forming one member of the weight connection. The links are madeconveniently as stout rods of an elongated S shape, the upper end ofeach being bentover, as at b, to hook into the hole h of the roller-hookH, and the lower oppositely-bent end has a laterally-enlarged head (2 Ihave shown the weight-carrier which 'constitutes the other member of theconnection as an elongated plate 0*, which is reduced inwidth at itsends to form at the lower end an upturned hook c, on which the weight Wis hung, and at the upper end two parallel ears c are extendedsubstantially at right angles work, and when the frame is in operationthe eccentric shafts are turned to lower the lifterbars, so that theweights W act through the intervening connections and the roller-hooks Hon the drawing-rollers. By a suitable handle L the shafts L can beturned to elevate the bars, so that their upper edges engage the bentfingers and raise the weight-carriers o so that the rollers are relievedof the pressure. The hooked end b of each link is passed through theslot 0 of its weightcarrier and the link is then drawn through until itshead I) bearsagainst the face of the weight-carrier, when the link isupturned between the ears 0 A cotter-pin 20 is then passed through theears outside the link, so that the latter cannot be accidentlydisconnected from its weight-carrier o while permitting a relativesliding movement of said members when the weight-carriers are raised bythe elevation of the lifter-bars L. i I have thus provided a two-partconnection between the weight and the corresponding roller-hook, soconstructed and arranged that when the .member 0* is lifted to relievethe roller from the weight the other member I) of said connectionremains in normal condition, and it is prevented from turning ortwisting by the ears 0 and the bent lower end of said member 17, passingthrough the slot 0 The construction is very simple, efficient,

and exceedingly cheap to manufacture, and the connection can beconveniently applied or removed when necessary.

In Fig. 1 I have shown by dotted lines the 5 elevated position of themember e of the extreme left-hand connection, the member I) remaining innormal position.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a drawing or spinning frame,top drawing-rollers and theircooperating hooks sus pended therefrom, lifter-bars, roller-Weights, anda two-part connection between each roller- I 5 hook and its weight, saidconnection comprising a weight-carrier connected with theweight andlongitudinally slotted at its upper end, an elongated, substantiallyS-shaped member having a head at its lower end and passed through theslot of the Weight-carrier, and means to retain said members togetherwhile permitting relative longitudinal movement, the weight-carrierhaving a bent, downturned finger to engage the lifter-bar, and the S-shaped member being connected at its upper end to the roller-hook.

2. Inadrawingorspinningframe,topdrawing-rollers and their cooperatinghooks suspended therefrom, lifter-bars, roller-weights,

and a two-part connection between each roller hook and its weight, saidconnection compris- "ing a flat plate having a weight-hook at its turnedbetween the ears and connected at its upper'end with the roller-hook,the downturned finger on each plate overhanging the 40 lifter-bar, to beraised thereby when the lifter bars are elevated. I

3. A weight suspending connection for drawing or spinning frames,consisting of a plate havinga hook at its lower end, parallel cars and alongitudinal slot at its upper end, and a downturned finger between itsends, combined with an elongated, substantially S-shaped'rod having anenlarged head at its lower end, said rod being passed through the slotand upturned between the ears of the plate, and a retaining-pin passedthrough the ears to prevent separation of the rod and plate.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES R. MCGOWAN.
